SPECIFICATION forming part of Letters Patent No. 438,247, dated October 14, 1890.

Application tiled May 6, 189th Serial No. 350,733. (No model.)

.To all whom t may concern:

Be it known that we, JAMES A. SMITH and SAMUEL R.LIBBEY, of Lincoln, Lincoln county, Kansas, have invented certain new and useful Improvements in Combined Oalf-Weaners and Cattle-Leaders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to a combined calfweaner and cattle-leader designed to be attached to the cartilage in the calfs nose, the parts of the weanr being so constructed as to interpose a barrier between the calfs nose and the cows udder whenever the calf attempts to suck.

Our invention consists of two semi-elliptical parts pivoted together and having knobs, which engage the cartilage in the calfs nose, the said parts being held in a locked position by means of aspring. One of these semielliptical parts is provided with a downwardlyprojecting lug having a hole through it, and the other with a lug projecting from its side, also perforated. A wire having a shield attached to it is passed through said perforated lugs, said wire being bent upon itself, in order to pass up through the side lug, where it is secured by means of a pin.

In the drawings which form a part of this specification, Figure 1 is a plan View of the semi-elliptical parts-wire and shield. Fig. 2 is a perspective view of the two semi-elliptical parts in their open position. Fig. 3 is an elevation of the shield secured to the pivoted wire, also showing the wire bent upon itself g and Fig. 4 is a view of one of the semi-elliptical portions, parts being broken away.

In the drawings, A and B are the semi-ellip tical parts, pivoted together at O, said parts A and B having a slight upward curve and being provided with enlarged or knob-like ends a and b, which serve to press against opposite sides of the central cartilage in the calfs nose. Of course it will be understood that a portion of the parts A and B is cut away at the point of pivoting, in order that this part of the device may be of substantially the same thickness as the rest. The part A is made wider or iiattened out at A2, and an eye a3 is formed therein. The other part B is also provided with an eye b', formed by a downwardly-extending perforated lug b2. The wire D is sharpened at both ends and has secured to it a shield D by means of rivets d and d. Said wire D is bent upon itself at d2. This bent portion is spread out, forming an eye. The part A has a channel or groove c,

(represented by dotted lines in Fig. 2,) anda spring c is secured therein by means of the rivet O, which pivots the parts A and B. The part A has a cut-away portion b3, having a recess b4. We prefer to makel the parts A and B as shown in Fig. 41that is, bend them so that the ends will fall outside of the plane of the perpendicular.

The operation of our invention is as follows: The parts all being secured together and locked, the operator places his thumbnail in recess b4 and raises the spring c clear of the shoulder formed by the cut-away portion b3 and pulls the parts A and B apart, the free end of the wire D adjusting itself by sliding in eye b2 as the parts A and B areA opened and closed. By a simple pressure of the hand after the device is properly placed with the knobs a and b in the calfs nose the parts close and lock themselves.

Having thus fully described ourinvention, what we claim as new, and desire to secure by Letters Patent, is-

In a calf-weaner, the combination of the semi-elliptical parts A and B,pivoted together, the groove c, a spring c', secured therein, a flattened portion a2, an eye as, formed therein, a cut-away portion b3, recess b4 in said cutaway portion, a lug b2 and eye b formed therein, with a wire D bent upon itself at d2, thus forming an eye, and a shield secured to said wire, substantially as described.

In testimony whereof We affix our signatures in presence of two witnesses.

JAMES A. SMITH. SAMUEL R. LIBBEY.
